Hey guys so I just built my first legit gaming PC but I'm running into a problem I can't seem to find a direct answer to anywhere.  Everything runs great under stock conditions but when I go to set my RAM to 3600 MHz under the XMP profile in the BIOS, I either can't boot or if I do boot, I'll get a BSOD with the code "Video_Scheduler_Internal_Error" within a minute or two of getting to the Windows home screen.
 
After researching, that error code seems to be a problem with the graphics card or the drivers which is strange to me since it runs games great at the stock 2133 MHz RAM speed.  I have tested the RAM separately and ran memtest86 and both sticks seem to be fine.  I only run into issues whenever I set my RAM to any speed higher than the default 2133 MHz.  The Nvidia drivers are up to date (457.30) and my motherboard's BIOS is also up to date. 
 
Maybe my PSU doesn't provide enough power for my components or is providing too much power due to the XMP profile overclocking voltage too high?  Or maybe my 1660 Ti has a faulty component?  Idk. Any help would be greatly appreciated so whenever I do get my hands on the 3070 through the step-up program in a few months, I'll have a great system that won't need to be updated for a few years.

This is a problem with a system memory error when using the XMP profile. AMD boards are notorious for not being able to use overclocked memory. Yes, XMP profiles are overclocking profiles. You might have better success trying to set the timings manually or use a lower speed manually such as 3400mhz with the same timings.

I've tried that but nothing is working.  I can't even get it to post. Whenever I save and exit from the BIOS after setting the timings (no matter how slow), the cpu tries to boot but within 1 second it will power off then reboot again.  On this 2nd reboot it takes longer than usual but eventually boots saying "memory overclock failed press F1 to enter BIOS".

Don't run 3600 speed on AMD hardware unless you're willing to first spend the time to learn all the settings to make it stable. Not even some tech reviewers can run it at 3600. XMP is not a guarantee of anything. You can probably get your system stable by running it at 3200Mhz without having to adjust anything else.

I seem to be able to get my system stable at 3400 mhz now by just setting the DRAM speed to 3400 mhz without activating the XMP profile and leaving everything else on auto.  I watched tons of videos and read a lot about manual timing but I can't seem to get it stable at anything above 3400 even when going with the safest timings and voltages.

3400 is more than fine, you're not going to see or feel the performance difference from 3400 versus 3600. Buildzoid from AHOC has some Ryzen DDR4 videos too, that may or may not help ya as he gets into secondary and tertiary timings I don't even know about. 
 
It's likely not the RAM itself. Part of the issue is the memory controllers have trouble running at a 3600 data rate. On AMD it's tied to the FCLK. I haven't gotten to play with a Ryzen rig yet. But keep an eye out for BIOS updates for your board, there's a new AGESA update AMD is working on that may make it possible to run at 3600 for most people, but it's something around two months out. 

Yeah I'm happy with 3400.  But up until a few days ago I was getting 2133 mhz when I paid for 3600 mhz sticks.  Even on my motherboard's official website it says it can runs speeds up to 4400 mhz lol hopefully a future BIOS update will allow me to be stable at 3600.  I want my rig to be upgradable for years to come which is why I got a b550 motherboard with 3600 mhz sticks of ram so I can upgrade my cpu and gpu without worrying about buying everything else. Thanks for your help!

What do the MB and ram QVL's say?

Hmm you may be on to something. When I went to my motherboard's website it supports the GSkill F4-3600C16D-16GVK ($150) and F4-3600C17Q-32GVK ($400) but not mine which is the F4-3600C18D-16GVK ($60).  I'm obviously not a computer engineer but I feel like it would be easier to support my cheaper, slower, more commonly used sticks of CL18 than the more expensive, faster, less popular sticks of CL17 or CL16.

I understand, but it's marketing stuff aimed at memory overclockers. Even AMD's newest 5000-series processors are officially rated for 3200MHz, so any frequencies above that is already an overclock beyond what is guaranteed. The future AGESA update AMD talked about might get 3600 stable for you, but otherwise the only other way is if you really start learning all the timings and manually tweaking them until it works.
 
In my personal opinion, the sheer time involved isn't worth a few percentage points. And running unstable RAM means you should only do RAM overclocking on a throw-away OS install, because it will corrupt files and drivers even if it is barely stable enough to boot into Windows. In fact I would suggest you run a Windows file verification on your system.. you can do by opening up an Administrator CMD prompt and pasting this to run it: sfc /scannow  I bet you it will find something.

True true hopefully that future AGESA update will get me to 3600 MHz but I'm not worried about it at the moment since I'm stable at 3400 MHz and getting great performance from my 1660 Ti while I wait months for my spot in the 3070 queue lol I was originally going to get 3200 MHz but I saw the 3600 MHz sticks on sale for the price of the 3200 MHz sticks so I jumped on it.  All I care about being able to run games at high FPS at 1440p 144hz refresh rate for years to come and 3200 or 3600 sticks would make little difference.  I just didn't want to eventually have a system with a beefy CPU and GPU be bottlenecked by RAM that couldn't get above 2133 MHz like I originally was stuck at since my original error was pointing towards the RAM while giving me an error code usually dealing with the GPU.
 
I ran that windows file verification before and didn't find any issues.  I just ran it again real quick and same thing.  No problems.

Interesting.  The g.skill QVL says it should work:

But no, it's really on a per kit basis.  On my MSI Z390 board, a cheap 3000CL16 2x16GB I bought wasn't actually supported and gave BSD errors when not down clocked, while the expensive 4000CL19 2x16GB kit I upgraded to works just fine (with a bit of voltage tweaks).
 
You can try increasing the appropriate voltages or using the Ryzen ram calculator tool.  Be prepared to do hours of research and testing.
 
Regardless, glad to hear you got it running at 3400mhz, that should be a benchmarkable 10%+ improvement in CPU performance vs. 2133mhz.
